“…Among vertebrates, the lack of understanding of neuroendocrine regulators of behavioral phenotypes is especially true among non-avian reptiles, as they are the least studied vertebrate taxonomic group (Kabelik and Hofmann, 2018), despite serving as an important evolutionary comparison group, especially for amniotic vertebrates. A social decision-making network has been described in reptiles (Kabelik et al, 2018), and various neuroendocrine variables have been related to the expression of social behaviors in lizards (Dunham and Wilczynski, 2014; Hartline et al, 2017; Kabelik et al, 2013, 2008b; Kabelik and Crews, 2017; Kabelik and Magruder, 2014; Korzan et al, 2001; Korzan and Summers, 2004; Larson and Summers, 2001; Smith and Kabelik, 2017; Watt et al, 2007; Sarah C. Woolley et al, 2004; Woolley et al, 2001; Sarah C Woolley et al, 2004). However, many potential regulators of social boldness remain unexamined.…”
